The VersaMix Multi-Shaft Mixer (photo) is designed for mixing pastes, creams and gel-type products, with the capabilities of powder dispersion, emulsification, dissolution, deagglomeration, homogenization, heating, cooling and deaeration. All of these functions are achieved in a closed system, without the need for any transfer steps. The mixer’s three-wing anchor, high-speed disperser and high-shear rotor-stator arrangement operate independently at different speed ranges to deliver uniformity in both low- and high-viscosity media. All product-contact surfaces are polished 316L stainless steel. The mixer cover includes multiple ports for charging raw materials and the installation of a vacuum or pressure transmitter, thermoprobe and tank light. It mates with a jacketed cone-bottom vessel that is designed for 100% discharge through a flush diaphragm valve. A 23-in. clearance from the valve outlet to the floor allows operators to position a bucket under the vessel to catch finished product after the mixing cycle. — Charles Ross and Son Co., Hauppauge, N.Y.
